ADH levels increase when an individual's plasma has become too dilute, and the insertion of aquaporins permits movement of water from the medullary interstitial fluid into the urine. True or False
Homework Answers
False.
ADH(Anti diuretic Hormone)-Vasopressin is a Hormone Secreated by Posterior pituitary when Plasma Volume is Low that is During Dehydration or when osmolarity is above 300 mOsm/L
ADH Acts on Collecting Duct------to the V2 receptors on the cell surface of tubular cells--- intracellular cascade that results in formation of water channel, aquaporin-2.
Through These water channels,There is Reabsorbtion of Water From The Filtrate(Urine) into the Interstitium then to Blood.
So that Loss of Water thrugh Urine is Reduced---More water is retained---Dehydration is corrected ---Plasma Volume Increases ---Osmolarity Decreases
